Secondary Condition Claim · VASRD 5025
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Fibromyalgia when it develops after Chronic Fatigue Syndrome (CFS).
Fatigue may coexist or be confused with muscle pain syndromes.
Primary condition · VASRD 6354
Chronic Fatigue Syndrome (CFS)
CFS causes persistent fatigue not improved by rest and worsened by physical or mental activity.
Secondary condition · VASRD 5025
Fibromyalgia
Fibromyalgia is a chronic pain condition marked by widespread musculoskeletal pain and tender points, usually with fatigue, unrefreshing sleep, stiffness and cognitive fog. VA rates it under DC 5025, and the percentage turns on how much of the time the pain is present and whether medication or therapy controls it — not on how many joints are involved.
The VA rates Fibromyalgia the same way whether it's claimed directly or as secondary to Chronic Fatigue Syndrome (CFS) — severity of Fibromyalgia itself determines the percentage.
Example combined rating
40% Chronic Fatigue Syndrome (CFS) + 20% Fibromyalgia = 52%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 20% combine to 52%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
